Running more than one instance of Evince

[Federico Fanton <federico panizzolo it>]

Hi everyone!
I have a wxPython application and I'm using Evince to display the 
reports it generates. Since I'd like to delete every report after the 
user has closed the corresponding Evince instance, my application uses a 
thread that does a subprocess.call() to invoke Evince, and then removes 
the report when the subprocess terminates.
This works fine as long as the user looks at just one report at a time, 
because if he opens one report and then another (without closing the 
previous one) the previous Evince instance gets "recycled" to show the 
new report, so subprocess.call() returns immediately and the file gets 
deleted too soon.
Is there a way to force Evince to use a new instance every time?
Many thanks!
